3 Claims.

This invention relates to an enameled metal wall corner construction and more particularly to a rounded corner construction using curved metal veneer panels.

In my copending application entitled Enameled metal wall construction, Serial No. 742,029, filed August 30, 1934, there is disclosed a construction wherein the enameled metal plates are prefabricated on insulation board backing so as to provide individual panels of metal veneered board that can be readily assembled in the construction of internal or external walls. Since there is no interlocking of the panels with each other, any panel can be quickly and easily removed from the face side without disturbing any of the adjacent panels.

The metal panels, which usually become warped at the high temperatures employed for burning on the enamel, are cemented under high pressure to rigid insulating boards, both for the purpose of pressing the enameled metal to straighten it out and also to eliminate the tendency of the metal to buckle under climatic conditions. Furthermore, the heavy insulating 25 boards not only prevent sweating of the metal but also act as sound deadener and heat insulation. In wall construction, these panels are supported in spaced relation and the resulting joints 7 are all caulked, so that no metal touches metal 0 and the edges of the panel are protected by a Waterproof caulking compound. All of the edges of the enameled metal panels are, at the same time, protected against rusting of the caulking compound.

My present invention relates to the use of this type of metal veneered panel in inside and outside rounded corner construction and contemplates the provision of curved metal veneered panels and of novel means for the assembly of 40 these panels topresent rounded corners of water tight construction and of pleasing appearance.

It is therefore an object of this invention to provide an enameled metal wall construction for rounded corners of a novel and improved type,

45 wherein the joints formed are water tight and present a pleasing and artistic appearance.

It is a further important object of this invention to provide a curved wall corner construction using metal veneered panels that are appropri- 50 ately curved to form segmental cylindrical wall surfaces having a common axis of curvature.

It is a further important object of this invention to provide curved metal veneer panels and 55 a rounded corner wall construction utilizing the same, together with suitable metal trim therefor of a standardized form and design.

Other and further important. objects of this invention will be apparent from the disclosures in the specification and the accompanying draw- 6 mgs.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown on the drawings:

The reference numeral I0 indicates a typical inner wall panel and the reference numeral ll represents a typical outer wall panel of my metal veneered construction. Since the construction of the two metal veneered panels is similar regardless of whether the panel is to be used in an outside or inside wall corner construction, the construction of the panel I!) only will be described.

Said panel I 0 comprises a curved porcelain enameled metal veneer l2 firmly cemented to a similarly curved insulation board backing l3. Since the metal veneer I2 is cemented to the insulation board backing I3 under high pressure, the two are practically inseparable and the backing of rigid insulation board tends to prevent the metal veneer from warping or buckling. The insulation board also acts as a sound deadener and as heat insulation. The metal veneer 12 extends beyond the margin of the insulation board backing l3 to provide extended portions l4 and I5 (Fig. 4) along opposite edges, such as the longer edges, and a flanged extension l6 along one of the other edges. (Fig. 3.) The fourth margin of the metal veneer 12 may be flanged or may lie in the same plane as the body of the veneer, as shown at ll, depending upon the position of the panel in the wall structure.

In constructing a rounded wall corner in accordance with my invention, a wooden frame structure is first erected, comprising vertical studding or other supporting members l8, base furring l9 and other furring Zll, the furring be" ing curved to conform with the desired contour of the rounded wall corner. As best shown in Fig. 4, the base furring I9 is provided with a length wise extending strip 2| along one face and flush with the bottom face of the furring. The furring 20 has a similar wooden strip 22 secured to one face thereof and extending for the full length of the furring. Each of the vertical supporting members i8 is likewise provided with a strip 23 extending full length along one face and medially thereof. In the case of the vertical support, such as the support 24 at a doorway or other opening, indicated generally by the reference character D, a strip 25 is secured along one face of the support 24 flush with the face of the strip along the doorway.

The inner and outer rounded wall corner supporting frame structures are arranged in spaced relation (Fig. 3) with braces 26 and 21 extending between pairs of vertical supports 18 and 24, respectively. The inner wall, indicated generally by the reference character A, is constructed by positioning the metal veneer panels I 9 in the openings provided between the horizontal and vertical supporting members, with the fiber board backing l3 abutting the adjacent portions of the facing strips 2|, 22, 23, and 25 in the case of the lowermost panel. The joints so formed are filled with a caulking compound indicated by the reference character C to provide water tight joints. The vertically extending facing strip 23 is provided with a keying groove 28 into which extend the marginal flanges of the adjacent panels. The groove 28 is then filled up with the caulking compound, which is initially plastic but sets in time.

The outer rounded wall corner, indicated by the reference character E, is built up with the metal veneer panels I l in a similar way, with the porcelain enameled metal veneer facing outwardly.

At the horizontal joint between adjacent panels Ill and H the marginal edges of the metal veneer overlap the facing strips 22 but are spaced apart to avoid metal to' metal contact. Metal retaining strips 29 are secured in place to overlie and conceal the margins of the metal veneer and then metal trim 30 secured over the retaining strip 29. For this purpose the metal trim 39 is provided with inturned flanges N that may be snapped over the lateral edges of the retaining strip 29 and resiliently held in place thereon by the inherent resiliency of the metal from which the trim 3B is formed. The joint inside of the retaining strip 29 is filled with the caulking compound.

A metal molding strip 32 is positioned along the base strip 2i of the inner wall structure A and a similar metal molding strip 33 is positioned along the face of the outer wall structure E. As best shown in Figs. 8 and 9, the inner molding strip 32 is formed of sheet metal with a vertical web portion 3A, a serrated flange 35 extending along the lower edge at right angles thereto, and a reversely flanged portion 35 extending along the upper edge. Some of the serrations of the flange 35 are provided with apertures 3'8 for receiving nails or other securing means, whereby the molding can be attached to the strip 2!. The reversely bent flange 36 is adapted to engage against the lower face of the metal veneer of the lowermost panel iii. The space between the vertical web 36 and the strip 2i is filled with caulking compound.

The molding strip 32a for the outer wall is of similar construction but with the serrated lower flange 35a extending along the inside of the curved molding instead of along the outside as in the case of the inside wall molding.

At the doorway D a metal sheet 39 covers the face of the inner and outer walls defining the doorway, the vertical margins of the strip 39 being flanged as at 8 and ll to overlie the strips 25. Retaining strips 42 (Fig. are secured, as by means of screws 33, tothe strips 25 so as to conceal the margins of the adjacent metal veneer and metal sheet 39. Metal trim Ml is then secured in place over the retaining strip, in the same manner as described with respect to the retaining strip 29 and metal trim 30.

A hanging stile 45 (Figs. 3 and 7) extends vertically along the metal sheet 39 to form a part of the doorway D. Said stile 45 comprises a wooden strip at through which extend nails or other securing means ll. A plane metal strip 48 is positioned over the head of the nails 41 and a decorative metal sheet 49 positioned thereover to cover the external surfaces of the strips 46 and conceal the metal plate 48. The metal sheet 49 may be first rolled to shape and the strips 46 and 48 inserted endwise therein. The purpose of the metal plate 48 is to permit the nails 41 to be driven into the braces 21 without marring the surface of the decorative metal casing 49.

A door stop, window stile, or the like, indicated by the reference numeral 50 (Fig. 6) may be constructed by encasing a strip of wood 5i with a decorative metal sheet 52 in much the same manner as described with respect to the stile 45.

It will be understood that other parts of the rounded Wall structure may be constructed in much the same manner as already described. For instance, a top molding similar to the bottom molding, strips 32 and 33, may be employed. The construction around windows will be in general like that described about the doorway D. It will be understood, of course, that the rounded inner and outer walls may be made up of panels having a greater or less radius of curvature and that the number of panels used will vary accordingly.

One of the advantages of my rounded wall construction is that the parts or elements may be largely standardized and prefabricated, so that the erection of the wall structures is relatively simple and does not require specially skilled labor.

Due to the use of a waterproof, plastic caulking compound, all of the joints formed .are perfectly water tight and practically permanent. It will be understood that metal trim may be used along either of the horizontal joints, as shown, or along the vertical joints, but it has been found most practical to use the trim on the horizontal joints and to use the caulking compound to finish the vertical joints. Stainless steel is preferably used for the metal trim and molding strip.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:
